The Development of Instructional Model by Using Problem-Based Learning with Multimedia to Enhance Problem-Solving Skills in Mathematics for Students in Grade 7

Abstract

The purpose of this research were to design and develop a problem-based learning model with multimedia to enhance problem-solving skills in Mathematics for students of grade 7 and to study the experimental results by using the problem-based learning model to enhance mathematical problem-solving skills.

The result of study;

1. The instructional model developed by the researcher consisted of 5 components: principles, objectives, contents, teaching and learning process, assessment and evaluation. The learning activities follow by 5 stages: (SDASP Model) 1) Syndicate and Identify the problem
2. Define the frame of educational problems 3) Action research 4) Summarize and Evaluation of the answers 5) Presentation and Exchange of Learning. The testing results of the instructional model were; (1) The development of Mathematical problem-solving skills of tudents;There were 25 students who pass the 75% criterion representing 86.21% of the total number of students. It is 75% higher than the established criterion. (2) The results of the comparisonof problem-solving skills of students after using instructional model were significantly higher than before learning at the level .05

(3) The satisfaction of students learning to use instructional model were at the high level.
